Foam formation ability of surfactants has been investigated with Molecular Simulation method. As the denotation of foam formation ability, interface formation energy (IFE) which is corresponded to the amount of foam film area of different systems have been investigated by considering the variation of film thickness, interfacial density and surfactant type. According to the results of experiment, the relationship between interface formation energy and foam formation ability has been built.

Key words: molecular simulation, molecular mechanics, interface formation energy, film area, foam formation ability
